The good news is it actually ran fine and there was no water in the tank, not a drop. Although the pistons and rods look pretty good after cleaning, the steel cylinder sleeves are quite scored so I plan to replace the rings for $30 and hone the crap out of the jugs. It's only scored where the rings traveled, the skirt area still has crosshatch. The crank bearings are tight and smooth and the journals are all smooth but I may use some 600 to shine them up, they are a little stained.
If this were a car (or a cub) i'd bore it out and replace the pistons or re-sleeve it but it just has to pump some air to run a few of my hobby tools.
